Standard material for bromine index determination

National Standard Materials: For example, GBW (E) 060114 petroleum bromine index determination standard material, which belongs to petroleum and chemical standard samples and solutions.

Standard materials for bromine index determination primarily include petroleum bromine index determination standard materials, among others. These are typically developed by specialized institutions or companies and are available in various concentration specifications. They can be used for instrument calibration, method validation, and other applications. The following is a detailed introduction:
National Standard Materials: For example, GBW (E) 060114 petroleum bromine index determination standard material, which belongs to petroleum and chemical standard samples and solutions. The light oil concentration range is selectable from 0.2 mg/L to 1,500 mg/L, and the heavy oil concentration range is selectable from 5.0 ppm to 5%. Additionally, there are GBW (E) 060115, GBW (E) 060116, GBW (E) 060117, and other series of petroleum bromine index determination standard materials.
Enterprise-developed standard materials: The bromine index standard materials produced by the Petrochemical Research Institute have concentration specifications such as 10 mgBr/100g, 57 mgBr/100g, 114 mgBr/100g, 460 mgBr/100g, etc., which can be used for coulometric determination of the bromine index in petrochemical products.
Other types of standard materials: According to ASTM 2710 standards, standard samples containing cyclohexene and toluene can be used for bromine index determination, with bromine indices of 10, 100, and 1000, respectively. Additionally, olefins such as octene and decene can also be used as standard materials for bromine index determination after dilution. For example, the theoretical bromine index value of octene is 543, while decene requires dilution with toluene before determination, and its bromine index can be calculated using relevant methods.
